Answer:
70/100
Step-by-step explanation:
Surface of the earth covered with water = 7/10
Equivalent fraction of 7/10 with 100 as the denominator = 70/100
This means 70% of the earth surface is covered with water
Percentage covered with land = Total percentage - percentage covered with water
= 100/100 - 70/100
= 100-70/100
= 30/100
Percentage covered with land = 30%
Answer:
A multiplied by E is like 12x 3=36
Normally when you're gathering sources it depends on what the topic is, what time or day, you try to find facts, and you see if there are any other useful information.
The widest are the ones with smallest fraction so the answer is C.
We can use ratios here. The real size would have to be proportional, meaning that if I increase the line on the drawing 5 times, the real size would have to increase 5 times as well.
We can obviously see, after having said that, that the real window would have to be 35ft long (because we multiplied 1 inch by 5, and if 1 inch represents 7 feet, then we also have to multiply that by 5 so it’s proportional, and 7*5=35)
We can check too — 1 in : 7 ft = 5 in : x ft
x = (7ft * 5in) / 1in — we would get the same result :)
